### Question
How to use Nacos to realize dynamic configuration in skywalking8
___
### Bug
- Which version of SkyWalking, OS, and JRE?
- Which company or project?
- What happened?
I use skywalking 8.2 to use Nacos 1.4.1, which are based on k8s deployment. When I configure Nacos and skywalking, I can find skywalking oapserver in Nacos server list. But the log has the following errors, which are thrown irregularly.
```

Skywalking is configured to connect Nacos as follows
```
nacos:
# Nacos Server Host
serverAddr: ${SW_CONFIG_NACOS_SERVER_ADDR:127.0.0.1}
# Nacos Server Port
port: ${SW_CONFIG_NACOS_SERVER_PORT:8848}
# Nacos Configuration Group
group: ${SW_CONFIG_NACOS_SERVER_GROUP:skywalking}
# Nacos Configuration namespace
namespace: ${SW_CONFIG_NACOS_SERVER_NAMESPACE:}
# Unit seconds, sync period. Default fetch every 60 seconds.
period: ${SW_CONFIG_NACOS_PERIOD:60}
# Nacos auth username
username: ${SW_CONFIG_NACOS_USERNAME:""}
password: ${SW_CONFIG_NACOS_PASSWORD:""}
# Nacos auth accessKey
accessKey: ${SW_CONFIG_NACOS_ACCESSKEY:""}
secretKey: ${SW_CONFIG_NACOS_SECRETKEY:""}
```
```
nacos:
serviceName: ${SW_SERVICE_NAME:"SkyWalking_OAP_Cluster"}
hostPort: ${SW_CLUSTER_NACOS_HOST_PORT:localhost:8848}
# Nacos Configuration namespace

This seems more like the usage of Nacos, than SkyWalking.
